Abstract
This study proposes the deriver assistance system to judge whether a passage (GO) or a stop (NOGO) at a signalized intersection ahead. The assistance system informs a driver visually of the distance which the vehicle can forward by maintaining the present velocity until the red signal. If the indicated distance is shorter than the distance to the intersection from the vehicle, the system also indicates a stopping distance by assuming the ordinary deceleration. By examining the driver simulator experiments, the assistance system realizes the earlier deceleration before the amber signal and prevents the emergency braking behavior.
